To all whom it may concern:

Be it known that 1, WILLIAM F. TUBESING, a citizen of the United States of America, and a resident of Gincinnati, county of liamilton, State of Ohio, have in vented certain new and useful Improvements in -Machines for Making Concrete Blocks, of which the following is a specification.

The object of my invention is a machine having a mold in which concrete blocks are formed, in which the operation of removing a block when formed from the mold makes a minimum amount of delay in the process of forming the next block therein, in which the movement of the machine automatically releases the block from the mold and carries it onto the unloading station and anton'iatit-ally closes the walls of the mold, which is provided with a means of supplying the proper amount of loose material to the mold uninterruptedly and which has an etiicient means of forming hollow blocks. This object is attained by the means described in the specification and illustrated in the accompanying drawings, in which,

Figure l is a plan view of a machine for making concrete blocks embodying my invention, the standards for supporting the engine which actuates the tamping block being omitted. Fig. 2 is a central longitudinal sectional view of the same taken upon line ;l2 t of Fig. 1. Fig. 3 is an end view, but showing the mold in sec tion upon line 111- 3 of Fig. 2. Fig. 4 is a detail perspective view upon an enlarged scale, of the reciprocating carriage, which has partitions for forming the ends of the mold and the tracks upon which is mounted the car which carries the block to form the bottom oi the mold. Fig. 5 is a detail perspective view of the swinging door which forms one of the sides of the mold between which the carriage reciprocates. Fig. 6 is a detail sectional view similar to Fig. 2, upon an enlarged scale, showing a modification for use in forming hollow blocks, the swinging ends of the carriage not being shown. Fig. '7 is a sectional view upon line zz of Fig. ti.

Referring to theparis: The mold consists of longitudinal non-reciprocating vertical sides, a, a. The fixed partition, I), of the carriage, l3, alternately forms the left and then the right hand end of the mold; the hinged sides, I), and b alternately forming the left and then the right hand end of the mold, the bottom of the mold being formed by a board, 6, which is carried upon one of the cars, 0, which is mounted upon the tracks of the carriage, ll, the top of the mold being formed by the tamper, D, which reciprocated by the engine, (I. The carriage, 13, is mounted upon longitudinal ways, e, of the frame, E. and is reciprocated by an engine, F, so as to bring the part ition, b, of the carriage alternately first to one end and then to the other end of the funnel, G, which is mounted upon the walls, a, a, of the mold. The carriage, B, is steadied upon its ways, e, by a longitudinal rod, E, which is secured to the ends of the frame, E, and passes through a longitudinal slot, B, in the carriage. The ends, b, b are hinged at b b, to the carriage and have their lower ends projecting downwardly so that when the carriage reaches either the left hand or the right hand end of its travel, the lower end of the doors, b, b come into contact with lugs, e, 6 of the frame and are thereby thrown outward as illustrated at the right hand sides of Figs. 1, 2 and 4. Rod, E, is enlarged at the center, 6 so that when the ends of the carriage have reached the innermost limit of their travel strikes the lower ends of the doors, b, If, and bring them to their vertical position, such as illustrated upon the left hand side of Fig. 2. The floor, b of the carriage is formed at an incline to the horizontal and has parallel tracks, 1), b 11 and 11 upon opposite sides of the partition, b, and formed at an acute angle to the sides of the carriage. When the carriage is at the right; hand limit of its travel, the tracks, b I), register with tracks, h, h of an unloading station, H, and when the carriage is at the left hand limit of its travel, the tracks, b I), register with tracks, k h of a second unloading station, H. The tracks, b b b and b receive cars, 0, with sets of wheels, the axles of which are placed in relation to the body of the car, such that when on the tracks, the board, 0, carried by the car, is on a level. At the sides of the funnel, G, are located two hoppers, M, M. of a size such as to accommodate a charge of loose material suflicient to form a block.

The engine, d, may be run by steam admitted through pipes, ul", (Z or by any other source of power, such as water under pressure.

Both non-reciprocating sides of the mold will be formed in one piece in those machines in which it is desired to make simply blocks having plain parallel faces. In case it is desired to make blocks having an outer face which has a configuration which is not plain, I form a hole in the wall, a, as illustrated in Fig. 5 and close the same by a swinging door, a which is pivoted upon a lug, (i projecting from the side, a, at the bottom of the door. When in position to close the hole in the wall, a, the door, a", is held by rods, a, a, which engage a rod, a, held by a stud, a which projects from the door, a. The inner ends of the rods, a a, engage lugs, a", which project from the sides, a. The rods, a, a have spurs, a a", which contact the door, w, to hold it in place. When it is desired to allow the carriage to reciprocate after a block has been formed, the rods, a, a are withdrawn from the rod, a, and the door may then be swung downward about the lug, a To the inner face of the door, a the form, a is secured. This form may be of any desired configuration to give the desired contour to the face of the block.

The operation of the device is as follows: When the reciprocation oi the engine, F, brings the partition, I), to the right hand side oi the iunnel, G, as shown in Fig. 2, the end, I), striking the block, a is brought to its vertical position. The charge irom either the hopper, M, or M, being discharged into the iunnel, G, the tamper, D, by the reciprocation oi the engine, tamps the loose material into the mold between the board, 0, the tamper, D, the partition, I), the side, I), and the non-reciprocating sides, a, a. It the block being formed has plain iaces, which will be the case when the form, a is plain, aiter the block has been termed, the engine, F, is actuated to move the carriage, ii, to the leit hand limit oi its travel, when the lower end oi side, I), will strike the lug, a, and be thrown outward. The newly iormed block being thus released iroin contact between the walls, I), and Z), gravity will cause the-cars, G, to move on to the tracks, If, h, oi the unloading station, H. The newly formed block is their removed irom the car and the car is moved upward upon the tracks, I), b. in the meantime, while this operation of removing the newly iormed block irom the left hand end of the carriage has been proceeding, the partition, I), having come to the leit hand end of the iunnel, G, and the end, having been carried to its vertical position at the right hand end of the iunnel by the block, 0 another blocl; has been iermed by the time the block has been removed irom the left hand end oi the carriage and the car has been placed back in position again. The carriage, ii, is then reciprocated to the right, as shown in Fig. 2, when the operation of removing the block iormed upon the right hand side oi the partition is carried on in a manuersimilar to that just described. Thus the operationoi torming a block is being periormed while the operation oi removing a block just iermed has progressed so that no time is lost in the use oi the machine. in ca. in which the configurated ierm, a is used, it is necessary to open the door, 06-, beiore reciprocating the carriage aiter the block has been formed.

In the form shown in Fig. 6, and Fig. 7 tor making hollow blocks, carriage, l3, has in its floor two perforations below which are two vertical posts, b, I), which are formed to enter the central bores in cores, R, l\'/. The carriage has upwardly projecting standards, I), I), upon which the lloor, If, is carried and the engine, F, in place oi being centrally located in reierence to the iramc, E is placed to one side and engages one of the standards, b, for reciprocating the carriage, l3. Horizontal bars, 0 c", are secured to the ends oi' the frame, E and have ledges, e, a. Ledges, a, c, stand upon each side of the posts, 1) I), terminate at points within the points to which the posts I), b, are carried when the carriage, 13 is moved to the leit hand and to the right hand limit ol its travel as shown in Fig. 6. Upon ledges, e, e, the cores, K, K, move when the engine rciproeates the carriage. To the ends of the iramc, l), levers, 0", a, are pivoted and the ends oi the lovers, 8 0, are bi-iurcated so as to straddle the posts, b I), when they are at the leit or right hand limits oi their travel, as shown in Big. 7. When the carriage is moved to the right hand limit of its travel, as shown in Fig. (3, core, K,being no longer supported by the bars, a 1, slides upon the post, I), carrying the lever, 0 downward. The car, C, is then tree to move on to the unloading station.

After the block has been removed and the car has been moved back upon the carriage, the core, K, is raised by means oi the lever, e to come to the level of the bars, 0 c and then the reciprocation oi the carriage, B will carry the core, K, onto the bars, 0 e. It will be thence borne to its position within the mold.
